I can't tell you what is causing this but you probably won't get a noticeable improvement by switching from 48 to 96 kHz. Your speaker system (and your ears) are probably incapable of resolving >20kHz signals in a live PA-type situation. Audio professionals ( mixers, mastering engineers, etc - not manufacturers ) are still undecided whether higher sampling rates is a good thing. If you are looking for higher fidelity sound, your time will be much better spent examining the gain stages of your system ( matching the impedances of inputs and outputs, etc ) rather than trying to get hicher frequency response though your DSP box. -Ben Loftis
